CORNER-BRACKET FOR BED-FRA1YIES.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed March 27, 1919. Serial No. 285,448.

1 '0 all whom. it may concern Be it known that 1, JOHN WALKER, of thecity of Toronto, in the county of York, in the Province of Ontario,Canada, have invented certain new and useful Improvements inCori1erBrackets for Bed-Frames, of which the following is thespecification.

h iy invention relates to improvements in corner brackets for bed framesand the ob ject oi the invention is to devise a corner bracket whichcannot work loose, in which all adjustments are made at the outside ofthe bracket where they can be readily gotten at, in which there are nodove-tail portions liable to fracture, which is so formed as to securelyhold the angle side bar of the bed either in the normal or invertedposition so that it will be impossible to have side play or work looseand in which the side bars of the bed frame may be connected theretowithout the use of special tools and it consists essentially of thefollowing arrangement and construction of parts as hereinafter moreparticularly explained.

Figure 1, is a perspective view of my corner bracket showing it attachedto a portion of a bed post.

Fig. 2, is a vertical section through Fig. 1.

Figs. 3 and 4e, are perspective details of the divided portions of thelocking block employed in connection with my bracket.

In the drawings like characters of reference indicate correspondingparts in the various figures.

1 indicates the bed post which is tubular. 2 indicates an inserted piecesegmental in form and adapted to fit within the tubular post 1 on thatside to which the corner bracket is to "be attached. The inserted piece2 is provided with orifices 2 and 2 in proximity to each end thereof. 3indicates my corner bracket which comprises a vertically disposedportion 3 having its interior face concaved at 3 longitudinally so as tofit the interior face of the bed post when set longitudinally thereof.The central portion of the interior concaved surface 3 is recessed at 3in order that the bracket may grip the bed post securely and have abiting connec tion thereto at each end. 3 and 3 indicate orificesextending through the portion 3* in proximity to each end thereof and inalinement with the orifices 2 and 2. 4.- indicates rivets which extendthrough the alined orifices 2 and 8 and 2 and 3 thereby securely andpermanently fastening the bracket portion 3* to the bed post.

8 indicates a. rectangular socket, which extends horizontally from theportion 3". 3 indicates an orifice formed in the portion 3 and in thebase of the socket 1 indicates an orifice formed in the bed post inalinement with the orifice 3. 2 indicates an orifice formed in theinserted piece 2 in alinenient with the orifices 1 and 3. 41- indicatesa bolt, which extends through the orifices 2, 1 and 3 and through therectangular socket 3" so as to protrude from the end thereof.

indicates a clamping or sec-Luring block which is divided diagonallyinto two portions 5 and 5 as will be clearly seen in full lines in Figs.3 and 4: and by dotted lines in Fig. 1. The plane of division not onlyinclines from front to rear of the block but also inclines from side toside thereby tending to force the portions 5" and 5 of the blocklaterally one of the other when forced together in the inserted positionwithin the socket. The block 5 is of such a size as to leave a spacebetween two sides of the block and the opposing walls of the socket 3*to permit of the insertion of the side angle bar 6 of the bed frame.

The outer end of the bolt 4* is threaded and provided with a wing not 7.5 and 5 indicate orifices extending longitudinally through the blockportions 5 and 5 in alinement one with the other and through which thebolt 4 extends, the orifices 5 and 5 being sufliciently large to allowthe free movement of the block in the direction required.

In securing the side bar 6 of the bed frame in position within thecorner bracket all that it is necessary to do is to loosen the wing nut7 upon the bolt 4;" so as to allow of free movement of the blockportions 5* and 5. The end of the bar 6 is then in serted in theposition clearly shown in Fig. l and the wing nut 7 tightened therebydrawing the block portions 5 and 5 together so as to move them outwardlyone from the other in an expanding direction toward the interior face ofthe socket 3* thereby clamping both the horizontal and vertical flangeof the bar against the corresponding wall of the socket.

In some cases it is desired to insert the side bars 6 of the bed framein an inverted socket 3*.

7 the block portions 5 and 5 upward and reinsert the bar 6 in theinverted position. The wing nut 7 is then retightened.

In order to carry the cross bar or the bed frame I have provided thesocket with an angle piece 8 extending outwardly therefrom and formedintegral therewith, the vertical flange 8 thereof being secured byrivets 8 to the vertical flange 9 of the crossbar 9.

- From this description it will be seen that I have devised a cornerbracket which can not work loose for the reason that the portions 5* and5 of the block 5 are wedged together in the socket 3 clamping the sidebar firmly in place, in which the connection of the corner bracket tothe bed post is provided without the employment of nuts located in theinterior of the tubular bed post. It is very common for these interiornuts to work loose and if such should be the case it is impossible foran ordinary person to retighten the bracket as it then requires aspecial tool which is inserted longitudinally through the bed post togrip the nut. In my construction of bed corner bracket any manipulationwhich takes place is done exteriorly of the bed post and,

therefore, can be performed by any ordinary person who is the user ofthe bed. It has also been found in ordinary constructions of cornerbrackets employing dove-tail joints thatthe dove-tails are liable tofracture at the neck or weakest part of the dove-tail. By myconstruction this dcfeet is eliminated. Also any holes in the side barsof the bed frame are dispensed with which are usually necessary forriveting and which tend to weaken the side bar at a point where thegreatest strength is necessary. By my construction also the side bar issecurely and positively clamped in position and can be readily heldeither in the normal or in the inverted position as desired. At the sametime I have provided a cheap and easily manufactured form of bedbracket.

What I claim as my invention is.-

The combination with the bed post, of a bolt secured within the bed postand extending through the wall thereof, a bracket having orificesthrough which the bolt passes, a side bar receiving socket carried bythe bracket, opposing wedge blocks fitting within the socket and havingalined orifices greater than the diameter of the bolt and through whichthe bolt loosely passes, the broad end of the inner wedge block bearingagainst the base of the socket, and a nut threaded upon the bolt andbearing against the outer end of the opposing block.
